time for a alternator upgrade.
look into
irragi alternators
High output alternators (the company)
powermaster
You should be looking for the highest amp alternator you can buy
270+ amps, should be about $400-$500
But that is the ONLY thing in the car that can make power, nothing else will make the power that amps is going to draw, period!
